I have had the vehicle in 4 times for check forward attendition warning system light keeps coming on. The first time they replaced the front camera. The situation came back after I was using the cruise control on a express way. Did not do it do it on the road but as soon as you stopped and turned the vehicle off the vehicle check forward attention warning system would come on and off and the only way to shut it off was to stop from more than 20 minutes and it would reset. Took the vehicle back 3 times and they could replicate so there was nothing they could do. The issue came back today. The check forward attention warning system light keeps going on and off. We stopped and let the vehicle sit and upon restarting the check forward attention did not reset . This time the vehicle lost all volume from the dash board. You could recieve phone but no volume. No radio volume. All the safety features that bing are not working. Check the set up and the volume had a red ??? next to the volume. 4 times into the shop for the same issur.

I am reporting severe safety risks and inspection fraud on my awd 2020 Hyundai Santa Fe (VIN: [xxx]) caused by universal Hyundai in orlando. Inspection fraud: the dealer falsified safety metrics, marking my brakes as a failing 4mm to push a $659. 90 repair (ro# xxx), then passed those exact brakes at 5mm eleven days later (ro# xxx). Tire malpractice: mechanics over-inflated my tires to a dangerous 39 psi and botched the alignment. This caused structural tire belt separation and severe sidewall bulges. The rear tire has suffered rapid, catastrophic deflation, dropping flat to 14. 5 psi and down to an empty 5. 5 psi. Crash & drivetrain risk: operating an all-wheel drive (awd) vehicle with a rapidly collapsing tire and asymmetric alignment forces the wheels to spin at mismatched speeds, creating severe friction that is destroying the internal powertrain transfer case and causing an immediate highway blowout crash risk. The service manager admitted "human error" and issued a full refund but banned my vehicle to avoid an audit. Hyundai corporate has been notified under case #xxx but has delayed resolution. Active consumer fraud file logged with the state of florida under case xxx. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have videos of these two incidents and others that I could not upload. While driving on the PA turnpike at 4:25pm on 5/22/26 75 mph my accelerator pedal stopped responding, my front collision warning light, engine, epb, and numerous other lights came on across my dashboard despite there being no contact with any object and my speed rapidly dropped. The front camera came on as if there was an object too close. I was in the middle lane. While I was trying to move to the shoulder there were tractor trailers behind me and to my right that began flashing their lights because my speed drastically dropped and was unable to safely stay with the flow of traffic in the heavy rain. While still in drive car started changing through notices on my digital screen "check blind-spot safety system" "check forward safety system" with the car crash icon, and "check driver attention warning (daw) system. " then I began trying to press the accelerator pedal again and the car would not move at all but the tachometer was going to 2x1000rpm. When I turned the car off and turned it back on again the engine light was still on, but the accelerator pedal was responsive. About an hour later when the tow truck driver from aaa attempted to drive the car on to the flat bed the accelerator pedal was unresponsive again. This was at least the fifth time my vehicle had lost propulsion without warning. Every prior time bowser Hyundai had different reasons for the failure, made a repair, and said it was safe to drive. Another incident occurred 4/7/2026 using cruise control at 84 mph when the car unexpectedly lost propulsion. The accelerator was again unresponsive, I was on the turnpike with two children in the vehicle. I steered towards the shoulder and the car slowed to a stop. After that incident, bowser Hyundai replaced the transmission on the car. They notified me on June 18 that they believe they fixed the problem again but I don't feel the vehicle is safe for my family and worry it will be deadly.

We were at full stop with auto hold feature enabled. Car lurched / jumped forward with no depression of the gas pedal. This caused us to strike the car in front of us.

I was at a standstill waiting for oncoming traffic to pass with my foot on the brake and all of a sudden the car accelerated and the forward collision warning fail to come on and I hit a trailer because of it.

Collision warning sensor alarm randomly comes on my dash and my car slams on the breaks. Very dangerous, I’m scared to drive down the highway going 60mph. 80,109 miles 2023 Hyundai Santa Fe. I have not brought it in to a Hyundai dealership because they want a diagnosis fee and everything else. Hyundai should fix it. This alarm has happened several times than it will go away and come on like 3 times in a row, usually daily when I use the car.

All normal sounds completely stop working, no audio or volume at all: no turn signal, no collision warning, no gps audio, no radio; no hands-free phone volume. Hyundai service department advised they have never heard of this type of incident. All warning systems are completely silent.

On a clear road a sencor comes on detect comes on says detection collision. The breaks come on when you are traveling on interstate or two lane roads. When you are traveling 75 mph and breaks come on all of a sudden on the highway. We are lucky we never got hit in the back of the car going that fast. We will stop 75 to 35 mph in 10 seconds.

Vehicle began to display front collision avoidance system error/ radar blocked. This also disabled the 'Smart' cruise control features. This happened any time the cruise control was engaged and we encountered traffic. The unit was in the dealer's service department for a week, and the front radar module was replaced and reprogrammed under warranty.

I own a 2025 Hyundai Santa Fe that was purchased on 08/15/2025. The first malfunction occurred on 08/25/2025, only days after purchase, and the vehicle has experienced repeated safety-related issues since then. The vehicle has repeatedly displayed false forward collision warning alerts, blind spot warning failures, park/neutral errors, and intermittent disabling of safety features. The most serious incident occurred when the vehicle unexpectedly entered “limit 20 mph” mode while I was pulling into active traffic with my toddler in the vehicle, limiting acceleration and creating a safety risk. I have also experienced false collision alerts while parked and after the vehicle was shut off. The vehicle has been taken to the dealership multiple times for diagnosis and repair attempts. Some issues were duplicated by dealership personnel, while other visits were documented as “could not duplicate. ” a front ultrasonic sensor was replaced, but the vehicle continued experiencing safety-related concerns afterward. During the repair process, I was informed and observed that dealership personnel appeared limited in what repair actions could be taken after consulting Hyundai through their diagnostic system. I was also informed that Hyundai influenced what could be included on service reports and that dealership personnel were instructed to “print the book” rather than fully document observed concerns. I believe this may have affected repair efforts and documentation of ongoing issues. The vehicle has been out of service for extended periods and the issues continue despite repeated repair attempts. Due to the ongoing malfunctions and inconsistent operation of the safety systems, I no longer feel safe driving the vehicle because I am concerned it may not function properly during a real emergency situation. Attached are photos of various dashboard errors and warning messages that occurred during these incidents to document the alerts and malfunctions experienced.

On two occasions, once at 70mph and once at 45mph vehicle suddenly lost power and displayed warning to check collision system, there were no vehicles close enough to warrant this. I had to limp the car to the side of the road as safely as possible and shut car off, wait a few minutes and restart vehicle to clear error and allow proper power/ acceleration again.

*problem parts:I only could check 1 box- should be brakes and steering too *adas: lane keeping assistance too over the course of two days, my 2020 Hyundai Santa Fe experienced a serious electrical and safety system failure. It started with the blind spot monitoring lights flickering in the side mirrors and warnings for forward collision avoidance (disabled), abs, electronic stability control, downhill brake control, parking brake & brake fluid (blinking red). The rearview camera failed and the screen remained on the radio display when in reverse. The lane keeping assist indicator shifted from white/green to orange. The next morning, I had trouble opening the vehicle with the key fob. Auto hold, master warning, forward collision, esc, and downhill brake control lights were now steadily on. The mph numbers on the dash were blurred, and a message appeared saying “put in p” even though the vehicle was already parked. The accessories light came on, but the engine would not start. Interior lights continued to work. I had to manually open the car and start it by pressing the fob to the button. While trying to exit a parking garage (where a tow truck couldn’t reach me), more warnings appeared: awd, low tire pressure, malfunction indicator (not engine), and power steering. I felt tightness in the wheel and had to pull over. The temp and gas gauges dropped to zero along with the rpms. I have a newer car battery and recently replaced fob batteries, so this was not a simple battery failure. I’ve reported the issue to Hyundai consumer affairs. No recall appears under my VIN, despite similar failures being widely reported in this model. I’m a single parent who typically drives with two young children, including one with serious medical needs. I rely heavily on this vehicle for medical travel. The vehicle has since been towed to a Hyundai dealership for diagnostics. This is a serious safety concern and could have led to a loss of control or failure in an emergency situation.

I purchased a new 2025my Hyundai santafe hybrid. Since the day of my purchase there has been a constant error message that is displayed on dash saying "driver attention warning system failure". This light stays on constantly and disables cruise control and adapative cruise system. This affects the usability of the vehicles. When asked Hyundai they say, drivers arent expected to wear sunglass if this system has to work properly, they even say constant blinking will cause system to fail and disable cruise control. This is a serious concern. How can people drive a car without blinking and how can a new car have disabled cruise control all the time.

Vehicle purchased 9/1/24 from courtesy Hyundai of tampa. Dealership failed to file registration/tags until 10/4/24. 7/12/vehicle experienced involuntary acceleration and braking, resulting in impact with my mother’s home. 7/16/dealer issued written report stating vehicle was operating normally and documented a recall-related display/audio/camera software update. 8/14/Hyundai engineering inspection performed without my knowledge. No report has ever been released. 8/27/Hyundai issued corporate denial, blaming driver error and stating braking/acceleration systems were normal. 12/5/second involuntary braking incident at highway speed on I-275. Five uncommanded braking events over ~20 miles. Service manager stated failure was due to sensor/camera malfunction and instructed that the vehicle should not be driven and to tow immediately. Despite this, the vehicle had been released into roadway operation. VIN lookup shows an open, unrepaired federal recall (24v879000 / recall 271) for the rearview camera system, marked recall incomplete, despite the dealer’s documentation that recall-related camera/software work was completed on 7/16/25. Bbb auto line denied my claim only because the vehicle was outside florida lemon law eligibility. No safety determination was made. Hyundai released no engineering, sensor, or camera data despite an engineering inspection. This vehicle has experienced repeated involuntary braking and acceleration at highway speed, involving braking, camera, and automatic emergency braking systems, creating a serious risk of loss of control, collision, injury, or death. Despite repeated failures, contradictory diagnostics, withheld engineering data, and an open federal recall, the vehicle was released back into public roadway operation. I request that NHTSA formally investigate this safety defect.

The “consider taking a break” warning comes on far too much and has almost made me wreck twice due to being startled.

The forward attention camera won’t turn off even when selected off in settings… I’m unable to drive comfortably with one hand at 12 o clock without constant beeps and warnings. Its maddening.

This is for the forward attention warning…. . This feature is misleading. I can be looking straight at the road and it will beep at me. We need a way to turn it completely off. This alone causes me to look at the camera instead of the road.

Our vehicle has twice gone from parking to drive and moved on its own! both times almost running over my wife.

This is a concern about the driver assistance warning consider taking a break 5 bell warning system. While we understand and appreciate the many safety features on new cars, we feel this feature is a safety distraction and hazard. We have turned this feature off in the driver assistance warning section and we have turned off the bell. Despite this, this warning with its 5 loud distinct bells sounds very frequently and often automatically disengages our cruise control while we are driving on the highway. In a recent vacation road trip of over 3,000 miles, the enjoyment of our trip and our new car was greatly compromised. During that time we tried to discern what actions we were doing to cause it to go off. It would go off when looking at the gauges so we would try to look quick and then eyes back on the road. We tried driving without sunglasses (which is a hazard itself), making sure our hands were at the 11 and 2 position, looking straight ahead. Nothing seemed to make a difference, it would go off randomly and often. Careful and safe driving requires a driver to scan the rear view and side mirrors, the gauges, be aware of other drivers proximity to your vehicle and avoid staring only straight ahead. I am aware that there may be consideration of a mandate for all cars with this feature in the future, however, as of the time of purchase of this vehicle, this law did not exist and as such, we should have the right to choose to use this feature or not. We have contacted Hyundai corporate and visited 3 dealers, none of whom would or could help except to tell us many others have voiced the same complaint. In our opinion this system as it currently operates is more of a hazard than a safety feature. We are seeking a software update or whatever means necessary to turn this feature off completely even when using cruise control.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving 55 mph, the forward collision avoidance warning alert system failed to operate as needed. The contact stated that the vehicle independently accelerated, and the contact depressed the brake pedal and the vehicle responded as needed. The vehicle was not taken to an independent mechanic or dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 133,000.

Three times this has happened. The instances occurred on highway 680 between pleasanton and san jose. I was going the speed limit - 65 miles per hour - as were tons of cars around me. Suddenly the car would brake, startling me because I was nowhere near another car. It frightened me a lot! I think it is the automatic braking system - either the front end collision warning or the blind spot collision warning. It could have easily resulted in an accident. I took it to the Hyundai dealership, and they knew they could not likely duplicate it. They showed me where to turn off the vehicle control (braking) for the front end collision warning and the blind spot collision warning. I have read on the internet several other parties that have experienced this - car-controlled braking while traveling at high speed with lots of cars around.

The forward collision assist would intermittently disable during driving. The lane keeping assist light illuminated and would not allow me to disable it causing the vehicle to drive straight only and to make left or right turns extremely hard to turn the vehicle. This incident occurred on [xxx] and was dropped off at johnson Hyundai in wake forest on that date. After a week of no contact of a diagnosis, I had to visit the dealer and was told the steering column was the issue and needed to be replaced. I contacted Hyundai America to report this issue and currently waiting on a response from their warranty to see if they will cover all or a percentage of the replacement of the steering column since my mileage is over their 100k (113k to be exact) coverage. While I appreciate their efforts, I also feel this could have resulted in a very serious incident had my daughter been driving on the highway when this occurred. Thankfully, she was picking me from home and it happened as we drove off from our house in our neighborhood. A steering column should outlast any other part(s) of a vehicle. If not, this is a huge safety concern. My [xxx] was also in the car at the time and I cannot even imagine how I would recover if something worse were to happen while he's on board. Hopefully this reporting will keep something bad from happening to others who own this type of vehicle but failed to report it. Thank you for your time.

The forward collision warning system engages and slows the car, often very abruptly, when on the highway and only when cruise control is on. It happens after we have been on the highway for a few hours, thus the dealer cannot reproduce the incident. It happens a few times on every road trip and is very disturbing when there are no other vehicles or obstacles in the road or nearby. We have reported this to the dealer several times and they can find nothing wrong. I provided a photo to the dealer of the dashboard showing the cruise control on, the forward collision system disengaged, and the forward collision warning activated. Dealer states they have recalibrated the system but can replace no parts unless a part is found to be faulty. The latest suggestion yesterday from the dealer was to "get out" of the car before the issue gets worse.

I am writing to formally express my deep concern and dissatisfaction with the ongoing quality and safety issues I have experienced with my 2021 Hyundai Santa Fe, which I purchased new in March 2021. Despite regular maintenance and careful ownership, this vehicle has presented a persistent pattern of failure—most notably involving the electrical systems, onboard cameras, and overall build quality. Specifically, the following issues have occurred: •the rear backup camera has intermittently failed for an extended period, frequently displaying a black screen or static lines, rendering it unusable. •the front camera system has now failed entirely, disabling several advanced safety features. A warning alert is permanently displayed on the dashboard and cannot be dismissed. •I was recently informed that repairing this front camera will cost approximately $2,400, a significant expense for a system that should not fail this early in the vehicle's life cycle. •the overall quality of the interior materials has proven to be poor, with excessive wear and inconsistent performance of various controls and features. •in general, the engine power and performance fall well below expectations, especially given Hyundai's advertised standards. These recurring issues have not only affected our driving experience but have also introduced serious safety concerns, particularly as critical systems such as cameras and driver-assist features are now non-functional. We have never experienced this extent of problems with any vehicle in our ownership history. At this point, we are extremely disappointed and frustrated, and we feel that Hyundai has failed to uphold the level of quality and reliability expected from a modern, family-oriented SUV.

Front radar system continues to not work without having damaged caused. Makes cruise control not work. Forward collision not work, etc.

I stepped on the brakes and all the aeb warning collision warning went on and I turn my car off and it still sounds like something is running.

I have taken my vehicle back into the dealership because my car will sometimes unlock itself, I am constantly having to check the doors to make sure they are still locked and most of the time it has unlocked itself. Most of the time I hear it unlocking as I am walking away. It is very disturbing. It also beeps as if another vehicle is going to crash into me and most of the time there aren't any vehicles anywhere near me. The phone charger does not work, I have been having issues with this from the beginning. The steering wheel also says I have to put my hands on the wheel when I have them on the wheel. I have a video of the car going a lot of rpms and it barely moved, a golf cart passed me up. The car also locks up sometimes when I am backing up. I drive my parents to san antonio for their dr. Appointments and am a little fearful of staying stranded either direction. My father is very ill and I am their driver. The dealer insists my car is the only one having these issues but I have read on reddit and other platforms of other Santa Fe's with similar issues. These issues do not occur all the time, but this does occur at the most inconvenience time.

The systems forward collision and lane departure warning are randomly turned off. Dealership is not aware of how to fix.

The front collision warning/assistance system on this vehicle does not appear to be working. The dealer claims that it is working. It seems that the protocol for testing for proper function is flawed and no one is tacking ownership of this issue. They are saying that in order to test the system a near collision must be imminent and to simulate this puts the technician at risk of injury (understandable); nevertheless, I have been in situations where I should have at least received a warning and there was none. On a test drive by the service manager with me in the vehicle the front collision assistance was verified on and active. The cruise control function was tested and worked to adjust the speed of the vehicle appropriately which tells me that assistance is available. It appears that the either the collision sensor is not recognizing collision danger or the danger message is not getting to the warning trigger and possibly the assistance trigger. This situation should be reported to the appropriate department a Hyundai for review.

This same scenario has happened 3 times since I purchased this vehicle - first event at mileage of 6273, 2nd event @ 7586 miles, and 3rd event @ 12,506 miles. All events were the same - while driving, dash board light start to flash and the vehicle looses all ability to accelerate. For each event, we have been able to coast out of traffic, turn the car off & restart. Once the car is restarted the acceleration works again, but the check engine light remains on along with an error code of p065312 possible power train issue. We have been very fortunate each time that we were on a road where we were able to coast out of traffic, but if this happened on a busy interstate or hwy traveling at high speeds we could have been rear-ended. The vehicle has been to the dealership twice for service and no problems have been found. The vehicle will be returned to the dealership tomorrow for 3rd service attempt.

My horn isn't working as designed but when I push on steering wheel feels like it's cracking or breaking behind it. My front axels from factory were out of balance causing a vehicle vibration from 80+km/hr. Dealer thought it was tires not driveline. Different dealer diagnosed it as both axels in front. Issue was repaired once parts were available. Vibration still is evident but think its tires. Trying to get Hyundai to replace tires now as its consequential damage. In November 2023 I was involved in a accident where the front collision warning and assist system didn't engage properly as when it did inwas in the danger zone already. And when I applied the brakes the steering became stiff as to mimic loss of power steering. I couldn't turn out of the accident and couldn't avoid it. Have video of this on my dash cam. I have a warning light rhat comes up on my dash saying check turn signal dealership verified. They have ordered the icu junction box (fuse panel) but its been on a back order. Till February now. But no stored codes ever stay on my ecu or bcm.

On three separate occasions over 18 months, the car has entered into front collision avoidance mode by unexpectedly swerving the vehicle and braking. Twice I was on the tollway doing 70 mph on a 4 lane expressway and I drove in between two tractor/trailer semis. When I reached mid point, the car braked heavy on it's own and swerved first the right, then to left. In each incident, not only did it scare the hell out of me, I thanked god I avoided a major accident from crashing into the trucks and or being hit from behind. In the third incident (date of this complaint) I was driving over train tracks on two lane road at about 35-40 mph, there were yellow black traffic barriers dividing the narrow roadway at the tracks and the car suddenly braked and swerved, nearly getting me rear ended and putting me down into the culvert around the tracks. In each incident it was difficult to take control of the car back from the collision avoidance.

First the check engine light was on and the vehicle was vibrating really bad and making a loud sound. Took it to the Hyundai dealership which claimed to repair the issue. While on my home from the dealership ( Hyundai of slidell), which was almost hours away, the vehicle lost power while driving. Later, multiple lights were illuminated on the dashboard including the epb, auto hold, forward collision, blind spot, check engine, and oil light. The vehicle is currently back at the dealership. Hyundai has been notified numerous times about the issue. This is a safety issue that needs to be resolved. Although there are no current recalls for this issue everything im experiencing with my vehicle are the same issues reported in previous recalls.

When traveling along the front collision warning system is triggered even though nothing is around the vehicle. The car remains running, but there is no response from the gas pedal. I have to coast to the side if possible or stop and turn on flashers (very dangerous on interstate highway). Once safely stopped, turning off the car and then starting again reboots the system and it runs fine until it happens again randomly. The check engine light stays on for a day, but does not light up the next morning. The dealership does diagnostics, but nothing shows up as wrong. It happens so fast there is no way to take a picture or video before the warning disappears. So far I have been lucky as this has happened at least 6 times. It is dangerous and I am terrified someone will not see flashers and run into me at highway speeds.
